"I've had customers who deployed SSL but kept their IPSec infrastructure up and running, usually for a select subset of power users," Fuller said. "The ability to do both IPsec and SSL transport on the same box is what's different," Fuller said. The flexibility provided by such a hybrid solution could bring cost savings to customers as they decrease their reliance on separate IPsec infrastructures, Fuller said. They will always have some sort of access," Ganitsky said.īy building dual transport capabilities into its SSL VPN line, Juniper is providing the best of both worlds, said Steve Fuller, president and CTO of Networks Group, a solution provider in Brighton, Mich. However, if traffic is blocked because of service provider problems or Network Address Translation issues, the system can automatically fall back to SSL transport, said Vivian Ganitsky, director of the security products group at Juniper, Sunnyvale, Calif. The upgrade enables users of Juniper's NetScreen Remote Access and Secure Access SSL VPN appliances to first try IPsec as the transport mode, tapping the high-performance benefits of that protocol. With the 5.0 version of Instant Virtual Extranet, the platform Juniper's SSL VPN family runs on, the vendor is adding a new dual-mode feature that can automatically switch between IPsec and SSL for transport.
